Question

Quizplus · Accepted Answer

A more massive terrestrial planet has a larger gravitational force, which allows it to hold onto an atmosphere more effectively. It also has a larger magnetic field, which helps to protect the atmosphere from being stripped away by the solar wind. Additionally, the interior of a more massive planet is hotter, which can lead to the release of gases that can contribute to the atmosphere. Finally, a more massive planet is more likely to have had a larger primordial atmosphere, which can provide a starting point for the development of a more substantial atmosphere over time.
